'BAILER.

Application led May 8,

`To all whom t may concern:

Be it known that I, ALEXANDER BoYN'roN, a citizen of the United States, and resident of San Antonio, in the county of Bexar and State of Texas, 'have invented certain new and useful Improvements in Bailers, of -which the following is aspeciication.

This invention relates to bailers especially adapted for use in oil wells. The invention has for one of its objects the provision of novel means "whereby the `downward thrust is utilized tointroduce the mud or other material into the bailer -through the main inletvopening in the lower end of the bailer and incidentally through ghe, openings in the opposite sides of the ailer.

In the practice of the invention, the in- A takeand discharge openings in the opposite sides of the bailer are exposed when theA bailer approaches the bottom of the well so as to receive the lighter mud, the heavier mud being introduced into. the bailer through the main inlet opening in the lower end thereof. l

Further the invention forming the subject matter of this application aims to provide a bailer having means whereby the discharge openings are uncovered simultaneously with the impact of the bailer on the sill of the derrick so that a maximum quantity of material may be discharged on each impact.

Further the invention operates to dump the mud` rapidly without removing the bottom, manipulating springs, pins orslots, thus saving a great deal of time in operation and adding greatly to the convenience of operation.

'40 lnoperation the invention forming the subject matter of this application does-not depart radically from established practices and consequently it will be favorably received when placed upon the market. l A further object is to provide a bailer having oppositely arranged discharge open-V ings, one of the openings being adapted for the reception of a steam or water hose while the other opening is adapted for the discharge of the mud sludge or other collected material and the steam and hot water -whereby thesteam whichv is introduced into the bailer for the purpose of loosening and 1922.

melting down the mud is discharged out through the other opening'alongwith themud.

A` further object is to 4provide a bailer which is reliablel in use, positive in action, and durable and cheap to manufacture.

Other objects and advantages of. the in-v vention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate likev parts throughout the same,

Figure 1 is a side elevation of the improved bailer,

Figure' 2 is a side elevation partly -in section.

Figure, 3 is a vertical longitudinal sectional view through the same,

Figure 4 is a section on line 4.-4 of Figure 3. p

In the drawing wherein for the purpose of illustration is' shown a preferred embodiment of the invention, the numeral 70 -designates an inner sleevewhich as illustrated in Fig. 2 has its lower end formed with a shoulder 7l with which a valve seat 72 contacts. The valve seat 7 2'is provided with a Hap valve 73 which allows mud to enter' the bailer and prevents the escape of mud thr-ough the lower end thereof at all times. The bailer bottom is designated by the numeral 74 and is threaded into the inner sleeve 70 adengages the lower side of the valve seat' 72 whereby to securely and positively hold the valve seat iny position. Thel lower end of the bailer bottom is exteriorly enlarged to form an annular shoulder. 75 .which limits the downward move-` ment of the outer sleeve. the bottom member 74 is liared as indicated at 76 so that the mud will be guided into the bailer when the bailer is thrustdownward.

When the bailer is introduced into vthe well, the thrust ofthe bailer is utilized as a means for forcmg the heavy ymud in The interior of loo through the bottom member 74 and through side slots.

As illustrated in Figure 3 an outer sleeve 77 is, slidable on the inner sleeve and is formed with a longitudinally extending slot 78 which receives 'a stop screw orpin 79 carried by the inner sleeve. rllhe stop screw or pin 79 serves as a means for limiting the movement' of the sleeves with 'relation' to each other and also serves as a positive means for preventing the loss of the inner sleeve. llt might be stated that the bushing 86 which is threaded into the forward portionu of the outer sleeve contacts with the forward portion of the inner sleeve. llt is thus seen that the pin 79 and the exteriorly threaded bushing 86 form a positive means whereby the disconnection of any of the parts is prevented and consequently the bailller may be withdrawn intact from the we lin .carrying out the invention the inner sleeve is provided with two oppositely arranged openin s 80 through which light mud is admitted into the bailer and through which all of the mud is discharged when the bailer is Withdrawn from the Well and thrust upon sill or dumping block. Also the outer sleeve 77 is provided With two oppositely arranged openings 81 adapted for registration with the openings 8() whereby light mud may be admitted to the bailer and whereby all the mud may be discharged. However, the openings 81 are brought into registration with the openings 80 only when the outer sleeve is advanced on the inner sleeve. A coiled spring 82-is confined between the rear end of the inner sleeve .and an annular shoulder 83 at the rear end of the. outer sleeve and the said coiled spring serves as a means for normally holdin the parts in the` position illustrated in Flgure 3, in 4which Figure the openings are not in registration. llt will be seen that the pinv 79 and the slot 78 insure registration of the openings 80 and 8l when the outer sleeve 77 is advanced.

`When the bailer is introduced into the well it passes through the light mud and when the bottom section 74C encounters the heavy mudLthe mud passes up past the valve 73 and into the bailer. When the bailer encounters the heavy mud the lighter mud is passed through the openings 80 and 8l' as at this period of the operation, the outer sleeve 77 has advanced against the tension of the coiled spring 82. The lighter mud which surrounds the .bailer and is under a considerable' pressure rushes in through the 'aligned openings 80 and 81 and thereby partly fills the bailer. vlWhen the bailer is `lilled it is withdrawn to the surface and as the-same is brought down on the sill `of the derrick, the openings 80 and 81 are brought-into registrationfsimultaneously with the im act sol that a maximum` quantity of mud 1s discharged.

With reference to the foregoing descriptlon, it will be seen that a bailer constructed in accordance with this invention does not involve a vradicalY departureA in operation from bailers now in use yand consequently the bailer will not be met with prejudice when placed upon the market.

ln dumping the material may be rapidly discharged from the bailer without first removing springs, bailer bottoms,pins and the like and without inconvenience on the part of the operator or attendant.

lf the mud will not readily' discharge itself through the aligned openings 80 and 81 a steam or water hose may be introduced into the bailer through one of the openings and the rsti" mud may be readily melt/ed down and discharged through the opposite opening without the returning steam being discharged upon the operators hands, as is the case when only one opening is available for this purpose.

Further, itwill be seen that the bailer bottom 74 is practically unlosable because the inner sleeve which contains the valve cannot be lost unless the outer sleeve bushing should be stripped out of its threads or be back-ed ofi', all of which is practically impossible, because of lock pin 85. The weight of the bailer.'v and the contents of. the same is not sufficient to strip the threads from thefouter'sleeve bushing 86 and the forward portion of the outer sleeve 77 and further the elasticity of the rsand line is sufficient to eectively absorb 'violent jerks and pulls. Also it will be seen that the bushing 86 is non-rotatably connected to the outer sleeve bymeans of pins or fastening devices 85.

Figure 3 illustrates that the lower end of the bushing is formed with oppositely located slots 87 to receive a tool or pieceot metal employed forthreading the bushing linto the sleeve 77.

llt is to be understood that the form ot the invention herewith shown and described `is to be taken as a preferred example-of the same and that such minor changes in arrangement and construction of parts may be made as will remain within the spirit of the invention and the scope of what is claimed.
